Hourmeter Programming OP7

OP7 is used in order to program the hours that are on the hourmeter.

Note: The hours can be increased but not decreased.

Note: The following procedure is applicable only to MUI or PEEC engines when the GSC+/GSC+P determines the value of the hourmeter on the display. The setpoint P023 is programmed to 0 or 1 and OP7 is available for programming. When setpoint P023 is programmed to 2(EUI engines) the value is determined by the engine ECM and OP7 is not available for programming.

The hours of a new GSC+ can be changed in order to match the hours of the former GSC+. OP7 allows the hours on a new GSC+ to exactly match the hours of the previous GSC+. This improves the tracking of engine maintenance when the GSC+ is replaced.

If the hourmeter shows all dashes, the hours can not be reprogrammed. See CID 268 if the hourmeter shows all dashes instead of a reasonable numeric value. CID 268 is within Testing And Adjusting, "Diagnostic Troubleshooting Codes".

Procedure For Hourmeter Programming

A new GSC+ w ith 0 hours is used as an example in the follow ing procedure. The example sets the hours to a value of 1234. If the value of the hours is increased, this procedure is valid.Note: Service Mode cannot be entered w hen the engine control sw itch (ECS) is in the AUTO position.

OP8 Setpoints (1) - Voltmeter Ammeter Programming

OP9 Engine Setpoint Verification

OP9 is the option for verifying that the EMCP II+ operates correctly

when a fault occurs with low oil pressure, high coolant temperature or

engine overspeed. An engine overspeed fault causes the GSC+ to shut

off the engine. When a low oil pressure or a high water temperaturefault is

detected the GSC+ will shut off the engine or sound the alarm according to

the programmed setpoint P003.

OP9 is only for verification of certain engine setpoints. OP5-0 is used for the actual programming of these setpoints. The setpoints that are verified by this procedure are listed below.

P003 Shutdown Override For Engine Fault - P003 is the GSC+ response to a low engine oil pressure. P003 is also the response to a high coolant temperature fault. 0 is for engine shutdown. If P003 is set to 1 then the alarm responds only. The GSC+ will over

P010 Engine Overspeed

P013 Low Oil Pressure Shutdown At Rated Speed

Note: When the oil pressure drops to a level that is within 34 kPa (5 psi) of the P013 setpoint, a low oil pressure alarm is issued by the GSC+ and the optional alarm module.

P015 High Water Temperature Shutdown

Note: A high water coolant temperature alarm is issued by the GSC+ when the coolant temperature rises to a level that is within 6°C (11°F) of the P015

The following conditions are required before the engine setpoints are verified.

The previously listed setpoints must be correct for the engine application. See System Operation, "Service Mode" in order to view a list of the setpoints. See System Operation, "Setpoint Programming OP5" in order to program the setpoints.

The engine is checked at idle and rated speed. No faults should be present at the initial starting. If necessary, troubleshoot and correct any fault.

Procedure For Programming Synchronization Setpoints

The generator set must be operating at rated speed when the technician is performing this

procedure. The parallel functions are available in OP11 by using the Parallel Mode Switch.

Note: If a parallel function is requested with the Parallel Mode Switch, the OP11 display will be

replaced by the display of the synchroscope while the synchronization is being performed. After

synchronization, the display will return to OP11.

High Water Temperature AlarmCoolant temperature increases to within6°C (11°F) of setpoint P015. Low Engine Coolant Temperature AlarmCoolant temperature decreases to setpoint P016. Low Engine Oil Pressure AlarmOil pressure drops to within34 kPa (5 psi) of the P013 or P014 setpoint. Fault Detected By Engine ECMThe engine ECM detects an alarm fault or a shutdown fault. Low Engine Coolant Level FaultCoolant level drops below the probe of the coolant loss sensor. High Engine Oil Temp FaultOil temperature increases to within6°C (11°F) of setpoint P026. Generator Overvoltage FaultLine to line voltages rises above the P102 or P105 setpoints. Generator Undervoltage FaultLine to line voltage drops below the P108 or the P111 setpoints. Generator Overfrequency FaultFrequency rises above the P114 or P117 setpoints. Generator Underfrequency FaultFrequency drops below the P120 or P123 setpoints. Generator Reverse Power FaultReverse power rises above the P126 setpoint. Generator Phase Overcurrent Fault Check for a cause of the overcurrent.Phase current rises above the P129 or P134 setpoints.

Check setpoint P029 and setpoints P128 through P135.

Generator Total Overcurrent FaultTotal current rises above the P131 or P136 setpoints. Phase A No Voltage Input FaultPhase A voltage not being received at GSC+ input. GSC+ Configuration ErrorFrequency of generator output voltage does not match engine speed.

Incorrect Phase SequenceThe generator and the bus have a phase mismatch. Improper generator or bus voltage 1. The generator voltage and the bus voltage must be above 10% of the

nameplate voltage in P028 when setpoint P020 is set to 700. Generator voltage and bus voltage must be above 50% of the nameplate voltage in P028 when setpoint P020 is set to any other v

The generator voltage or the bus voltage are either too low or the voltages do not match.

2. Check Setpoints P303 and P304 in order to determine whether the generator voltage and the bus voltage match within the tolerance that is specified.

Synchronizer Time-OutThe GSC+P is unable to complete automatic synchronization or dead bus paralleling within the time allowed in P314.

AL18 Check for cause of synchronization time-out. Ensure that the engine is responding properly to the GSC+P Speed Adjust 1 Output signal. Check for wiring errors. Check setpoints P313 and P314 for proper values. Increase the values, if necessary.

Additional AL Fault Codes (for GSC+P) AL16 Check for the cause of the phase sequence mismatch. Check wiring to

the bus transformer box (BTB +) and the AC transformer box (ATB +).

AL17

AL14 Check for an open circuit on the wire that is connected to the GSC+ connector contact 10. Check for a short on the wire that is connected to the GSC+ connector contact 10. See the Testing And Adjusting,

AL15 Check setpoints P009 and P033. Setpoint P009 represents the number of ring gear teeth. Setpoint P033 represents the number of generator poles. Correct the setpoint value, if necessary.

AL11 Refer to the engine service manual for a cause of lost engine power. Check setpoints P125 through P127.

AL12

AL13 Check for a cause of the overcurrent. Check setpoint P029 and setpoints P128 through P137.

AL9 See the Troubleshooting, "Indicator For Engine Overspeed". Check setpoints P113 through P118.

AL10 Refer to the engine service manual for a cause of low engine speed. If engine speed is reduced and the ECS is NOT in STOP, the GSC+ will issue this fault. Check setpoints P119 through P124.
